I have not heard any of those myself. If you're after SQ, then I'd start with the more recent stuff. Things like Ellington may be grainy.
Personally, I'd go with the original albums before I'd go with compilations, even if that meant red book.
Benny Carter - Jazz at the Philharmonic at the Montreux Jazz Festival 1975
Zoot Sims with Joe Pass - Blues for Two
Joe Pass with Jimmy Rowles - Checkmate
Stan Getz With Zoot Sims - The Brothers
Zoot Sims with Jimmy Rowles - If I'm Lucky / I Wish I Were Twins
Bill Harris With Ben Webster and Jimmy Rowles - Bill Harris and Friends
Zoot Sims with Harry "Sweets"Edison - Just Friends
Zoot Sims - Soprano Sax / The Swinger / Zoot Sims and the Gershwin Brothers / The Innocent Years / Passion Flower: Zoot Sims Plays Duke Ellington
I find it amazing that the Democratic Congress has lower favor with the American people than Dubya. People hate Dubya. That really says something to me.
I'd skip the Meridian. People who's opinions I respect hate it.
For a source of some sort, I'd go with a Bel Canto Dac3. People who's opinions I respect love it.
